Dysautonomia, or autonomic nervous system dysfunction, was diagnosed in a 1-year-old dog. Clinical signs of disease included diarrhea, vomiting, prolapse of nictitating membranes, and urinary incontinence. Bilateral keratoconjunctivitis sicca, xerostomia, and decreased anal sphincter tone were also observed. On the basis of response to atropine, results of intradermal histamine testing and gastric motility studies, and ocular response to parasympathomimetics and sympathomimetics (direct and indirect acting), autonomic nervous system function was determined to be abnormal. Treatment with metoclopramide hydrochloride and bethanechol chloride resulted in improved attitude, appetite, Schirmer tear test response, and decrease in frequency of vomiting within 24 hours. Bladder function and anal tone improved within 3 weeks.

Autonomic dysfunction was diagnosed in a 2.5-year-old spayed domestic shorthair cat. The cat had an 8-day history of progressive anorexia, signs of depression, constipation, weight loss, and intermittent regurgitation. Physical examination findings were signs of depression, dehydration, cachexia, bradycardia, bilateral nonresponsive mydriasis, prolapse of both nictitating membranes, dry oral and nasal mucous membranes, and urinary bladder atony. Thoracic radiography revealed megaesophagus. The cat lacked esophageal motility and had a decreased gastric emptying rate. Providing adequate fluid intake, electrolyte balance, and nutrition is a major problem in the management of dysautonomic cats. We were able to provide adequate nutritional support for this patient, using total parenteral feeding and, later, enteral nutrition using a nasogastric tube. Results of an ocular pharmacologic study indicated that the mydriasis and prolapse of the nictitating membrane were attributable to complete autonomic denervation of the eye. Using the method described, topical, autonomic-stimulating agents may assist the clinician in diagnosing dysautonomia in the feline. This report describes a syndrome that is well recognized in the United Kingdom and has the potential to develop in the United States.

Systemically injected anti-acetylcholinesterase antibodies in rats cause selective lesions of preganglionic sympathetic neurons. Adult rats were examined up to four months after a single i.v. injection of murine monoclonal acetylcholinesterase antibodies or normal immunoglobulin G (1.5 mg). Within 4 h, antibody-treated rats developed ptosis, a sign of sympathetic dysfunction that was never reversed. Persistent pupillary constriction reflected preserved and unopposed parasympathetic function. Weight gain was depressed, but locomotor activity, excitability, and sensorimotor responses were normal, and gross neuromuscular performance was near normal. These findings were supported by biochemical evidence for selective sympathetic damage. Acetylcholinesterase activity was reduced for the whole period of observation in sympathetic ganglia and adrenal glands but fell only transiently in muscle and serum. At all times, choline acetyltransferase activity (a marker of presynaptic terminals) was unaffected in muscle but grossly depleted in ganglia. Light and electron microscopy showed that preganglionic sympathetic terminals of superior cervical ganglia were severely damaged while parasympathetic ganglia were less affected and motor endplates of skeletal muscle were apparently spared. Immunocytochemistry revealed punctate deposits of murine immunoglobulin G and complement component C3 in ganglionic neuropil 12 h after antibody injection. This finding was consistent with complement-mediated lysis of preganglionic terminals. Morphometric analysis of preganglionic neurons in the intermediolateral nucleus of the spinal cord showed progressive loss of cholinergic perikarya over several months. We conclude that antibody-induced destruction of ganglionic terminals leads to death of preganglionic sympathetic neurons and, hence, permanent dysautonomia.

RECENT DESCRIPTION: Recent report have described "atypical" familial extrapyramidal syndromes similar to authentic Parkinson's disease and well-defined genetic diseases. PERRY SYNDROME: Onset occurs between 35 and 57 years, leading to death within 3 to 7 years. The syndrome associates a Parkinson's syndrome, athymormia and hypoventilation. Massive neuronal depopulation in the locus niger and rare Lewy bodies are seen. PARKINSON'S SYNDROME WITH PERIPHERAL NEUROPATHY: In addition to the extrapyramidal signs, there is ptosis, neuropathy and sometimes dementia and major neurone loss in the locus niger. No Lewy bodies have been identified. PARKINSON'S SYNDROME WITH PALLIDOPONTONIGRAL DEGENERATION: Onset occurs between 32 and 58 years, leading to death within 8 years. Extrapyramidal signs, falls, supranuclear palsy and dementia are observed. Neurone loss is severe in the pars compacta, locu sniger, palladium, pons, and mesencephalic tegmentum. There are no Lewy bodies. EARLY-ONSET PARKINSON'S SYNDROME: Beginning between 2 and 39 years, there are no associated neurological signs. Severe neurone loss in the pars compacta and the pars reticulata of the niger locus without Lewy bodies. PARKINSON'S SYNDROME-DEMENTIA WITH "BALLOON NEURONES": This syndrome begins at 24-59 years and leads to death in 8 to 11 years. There are extrapyramidal signs, a pyramidal syndrome, dementia, generalized seizures and dysautonomia. Major neurone loss occurs with balloon neurones in the anterior temporal cortex, the amygdala, the parahippocampal gyrus, the hypothalamus, the dorsal nucleus of the X and rare Lewy bodies. PARKINSON'S SYNDROME FRONTAL DEMENTIA AND AMYOTROPHY: Beginning between 27 and 56 years, the syndrome leads to death in 13 years and associates frontal dementia with motor neurone defects with the extrapyramidal signs. There is neurone loss in the locus niger and amygdala as well as in the anterior horn of the cord. There are no Lewy bodies. SPECIFIC CLINICOPATHOLOGICAL ENTITIES: is the most likely hypothesis. There is no anatomoclinical evidence suggesting these syndromes should be considered to be Parkinson's disease.

We present a patient with postinfectious dysautonomia, which developed 2 weeks after a meningoencephalitic episode. The chief dysautonomic symptoms and signs included constipation, urinary dysfunction, anhydrosis, ptosis, and orthostatic hypotension. Neurophysiologic studies revealed no involvement of the somatic nervous system. The dysautonomia recovered gradually 3 months later with minimal supportive treatment.

PHACE syndrome classically presents with a large, segmental facial infantile hemangioma (IH) associated with structural and vascular abnormalities involving the head and neck, heart, and eyes. We evaluated an infant who presented with ptosis caused by a clinically subtle, deep right-sided periorbital IH identified on MRI that also incidentally revealed hypoplasia of the right common carotid and right internal carotid arteries, supporting a diagnosis of PHACE syndrome. She subsequently developed acute-onset, transient right-sided facial erythema without anisocoria, triggered by feeding and emotional stress. We believe this represents a Frey syndrome-like developmental dysautonomia, previously unreported in association with PHACE syndrome, suggesting an associated defect in neurovascular embryogenesis.
